And, I wish we could find a way to teach people in the modern world that does not require violence.

When I played AD&D as a kid, it was not about violence. It was about exploration. There is a big difference.

My mom attributed my advanced reading skills from reading AD&D manuals. I learned a lot. People can learn, but I am confused as to why learning needs to occur within such violent contexts. This is great for creating world crushing companies, but will this type of startup make better people and a better world?
